surface of the planet at
equatorial locations (water ice is known to exist near the
surface at the poles).
Head does not expect to find the same icy cover in the
equatorial regions of Mars where Spirit and Opportunity landed, but he hopes the «scratch and sniff» tests — in which the rovers drill into Mars rocks and compare the
surface with the interior — will reveal the climatic history of the region.
Rising air over the Atlantic subsides over the
equatorial Pacific, causing central Pacific sea
surface cooling, which in turn reinforces the large - scale wind anomalies.
As a result, the Earth's
surface may have froze mostly or thinly solid through
equatorial regions («Snowball» versus «Slushball» Earth hypotheses).
The higher sea level near the western ocean boundary creates a west - east pressure difference in the ocean, that results in the
equatorial undercurrent flowing from west to east below the
surface.
The increase in sea
surface temperature over the central and eastern
equatorial Pacific known as El Niño, and the corresponding decrease known as La Niña, contribute to seasonal climate and weather fluctuations in many regions of the globe.
Earth's
surface may have froze mostly or thinly solid through
equatorial regions (see debate between the «Snowball» versus «Slushball» Earth hypotheses).
To learn more about

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides
surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the
equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land
surface for erosion... etc..
